VMware is a virtualization and cloud computing software provider for x86-compatible computers. VMware Inc. is a subsidiary of EMC Corporation and has its headquarters in Palo Alto, California. VMware virtualization is based on the ESX/ESXi bare metal hypervisor, supporting virtual machines. The term "VMware" is often used in reference to specific VMware Inc. products such as VMware Workstation, VMware View, VMware Horizon Application Manager and VMware vCloud Director.
VM, which stands for "Virtual Machine" (not to be confused with the broader term virtual machine), is a widely-installed operating system for IBM-compatible computers and servers that can host other operating systems in such a way that each operating system behaves as if it were installed on a self-contained computer with its own set of programs and hardware resources.
